DETAILED DESCRIPTION OF THE EXEMPLARY EMBODIMENTS

In order to make the above-mentioned objectives, features and advantages of the present disclosure more obvious and easy to understand, the specific embodiments of the present disclosure will be described clearly and completely below in combination with the accompanying drawings. Obviously, the specific details described below are only a part of the embodiments of the present disclosure, and the present disclosure can also be implemented in many other embodiments different from those described herein. Based on the embodiments of the present disclosure, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present disclosure.

It should be noted that when an element is referred to as being “fixed to” another element, it can be directly on the another element or provided therein. When an element is considered to be “connected” to another element, it can be directly connected to the another element or provided therein at the same time. The terms “vertical”, “horizontal”, “left”, “right” and similar expressions used herein are for illustrative purposes only, and do not mean that they are the only embodiments.

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those skilled in the technical field of the present disclosure. The terms used in the description of the present disclosure herein are only for the purpose of describing specific embodiments, and are not intended to limit the present disclosure.

In one embodiment, please refer to FIG. 1, a simulated rowing machine may include a front moving assembly 1, a rear moving assembly 2, a track 4, and a linkage 3; both the front moving assembly 1 and the rear moving assembly 2 may be movably connected to the track 4; the linkage 3 may be a closed loop with two linear moving paths tensioned by the transmission wheel 9 at both ends. The closed loop may be roughly parallel to the track 4 and include a first moving path and a second moving path, respectively. The front moving assembly 1 and the rear moving assembly 2 may be respectively fixedly connected to the first moving path and the second moving path, and the front moving assembly 1 and the rear moving assembly 2 may be driven in opposite directions when the linkage 3 rotates periodically.

In the present disclosure, both the front moving assembly 1 and the rear moving assembly 2 may be movably provided on the track 4, and a tensioned closed-loop linkage 3 may be used to realize the linkage of the two assemblies in opposite directions. During exercise, when the user's foot pedals forward to move the front moving assembly 1, the user sits on the rear moving assembly 2 and moves backward with the driving of the linkage 3; when the foot is retracted, the linkage 3 drives to the rear moving assembly 2 to move forward. Through the linking of the linkage 3, the user can exercise the muscles of the legs, waist, upper limbs, chest, and back at the same time, such that the rowing scene can be well simulated and the user's overall coordination can be exercised.

In an embodiment of the present disclosure, referring to FIGS. 1, 2 and 3, the linkage 3 may be a chain, and the chain may include an upper chain as a first moving path and a lower chain as a second moving path, the upper chain and the lower chain are arranged to make the closed loop parallel to the lower end of the track 4. The front moving assembly 1 and the rear moving assembly 2 may be respectively connected to the chain, and the fixed positions of the front moving assembly 1 and the rear moving assembly 2 may be different half sections of the closed circle to make the two moving assemblies move in opposite directions.

It can be understood that the use of a combination of a chain and a sprocket can ensure the strength of the linkage 3 and avoid slippage between the linkage 3 and the transmission wheel 9. The upper and lower sections of the chain are arranged so that the chain may be covered by the downward projection surface of the track 4, such that the chain can be protected from being touched by the user when it rotates, the normal rotation of the chain can be protected, and use of space may be more reasonable.

As long as the front moving assembly 1 and the rear moving assembly 2 may be, of course, in different half sections of the chain, the reversed traction function of the front moving assembly 1 and the rear moving assembly 2 can be realized, such that the movement of reciprocating extension and contraction of the user's body can simulate the movement of rowing and achieves a good exercise effect.

In addition, the arrangement of the chain is not limited to the upper and lower settings. For example, the arrangement of the chain can also be arranged in two sections on the left and right, and the front moving assembly 1 and the rear moving assembly 2 may be respectively arranged on the left and right sections of the chain, it can also realize the movement of the two moving assemblies in the opposite direction, and at the same time, the height of the rowing machine can be reduced by the way of left and right arrangement.

In order to ensure that the relative positions of the two moving assemblies on the chain can be adjusted, both the front moving assembly 1 and the rear moving assembly 2 may be locked on the chain by screws. Due to the detachable and adjustable characteristics of the screw locking, the distance between the front moving assembly 1 and the rear moving assembly 2 can be adjusted according to the user's height, arm span and other factors, such that the user can exercise more scientifically and comfortably.

In another embodiment, referring to FIGS. 6, 7 and 8, the front and rear ends of the track 4 may be respectively provided with a front roller assembly 6 and a rear roller assembly 5. Both the front roller assembly 6 and the rear roller assembly 5 may be sleeved with a transmission wheel 9 on the roller shaft 52, the transmission wheel 9 may be in transmission connection with the linkage 3. The linkage 3 drives the front roller assembly 6 and the rear roller assembly 5 to roll on a rolling track 7 through the transmission wheel 9. The rolling track 7 may include a front rolling track 71 and a rear rolling track 72. The front rolling track 71 and the rear rolling track 72 may be fixedly connected by a connecting rod 8. The front roller assembly 6 may be rollingly connected to the front rolling track 71, and the rear roller assembly 5 may be rollingly connected to the rear rolling track 72.

It is understandable that through the arrangement of the rolling track 7, when the user is performing a simulated rowing, the roller drives the equipment to move on the rolling track 7 under the drive of the chain. It can better simulate the rowing scene and exercise the coordination of users.

The rolling track of the embodiment may be two small sections connected by the connecting rod 8. The rolling track enables the front and rear roller assemblies 5 of the rowing machine to roll on the pulley frame, such that the volume of the rowing machine rolling track 7 can be reduced and the cost of materials can be saved, with an easy disassemble and transportation. The arrangement of the front and rear rolling tracks can facilitate the setting of different widths of the front and rear rolling tracks, so that the front and rear roller shafts can also be set to different. For example, the diameter of the roller 51 of the front roller assembly 6 may be smaller than the diameter of the roller 51 of the rear roller assembly 5, and the roller shaft 52 of the front roller assembly 6 may be longer than the roller shaft 52 of the rear roller assembly 5. It can be understood that the width of the corresponding front rolling track 71 is also greater than the width of the rear rolling track 72. Because the equipment is prone to shaking when the user uses the rowing machine to exercise, in order to ensure the stability of the rowing machine, the technical solution sets the lengths of the front and rear roller shafts 52 to different lengths, and the wheel diameters are different, such that an substantially triangular stable structure can be formed. At the same time, the present embodiment also places the front rolling track 71 and the rear rolling track 72 on the same horizontal surface. Due to the different diameters of the front and rear rollers, the user needs to overcome the gravity to climb the slope when exercising, thereby improving the user's exercise effect. At the same time, a reduction transmission system such as a gear box can also be added between the linkage 3 and the roller shaft 52, to increase the amount of movement of the user and balance the rotation of the front and rear rollers.

Referring to FIG. 9, the front moving assembly 1 and the rear moving assembly 2 may be respectively fixedly connected to the linkage 3 through a connector 8. The connector 8 may include two front and rear fixing pieces 81 and two left and right splints 82. The two splints 82 may be fixedly connected with screws through the fixing pieces 81. The top of the connector 8 and the lower side of the front moving assembly 1 or the rear moving assembly 2 may be fixed to each other by screws. Both the left and right splints 82 may be provided with small clamping parts 83 extending in the middle direction. The linkage 3 may be fixed and clamped by two clamping parts 83. The upper half section 31 or the lower half section 32 of the chain may be clamped by the clamping part 83, such that the two sections of the chain can be protected from interfeloop with each other, and the upper and lower half sections of the chain can be prevented from being entangled when the chain is loose, in order to ensure the normal periodical rotating of the chain.

Among them, the connector 8 may also include two upper horizontal shafts and a lower horizontal shaft. The left and right ends of each of the upper horizontal shaft may be respectively fixedly connected with two splints 82. The upper horizontal shaft may be sleeved with a rolling shaft sleeve 84 rollingly connected to the track. The left and right ends of the lower horizontal shaft may be respectively fixedly connected with two splints 82, and the rolling shaft sleeve 84 may be also sleeved outside the lower horizontal shaft. The lower horizontal shaft may be provided below the upper horizontal shaft, and the track 4 may pass through a position between the upper horizontal shaft and the lower horizontal shaft. The rolling shaft sleeve 84 allows the front and rear moving assembly 2 to move smoothly on the track to avoid frustration, and the lower horizontal axis can also limit the front and rear moving assembly 2. The lower horizontal axis not only serves to mount the rolling shaft sleeve 84, but also functions as a limit for the track 4.

The connector 8 may also include two hanging arms 85, the clamping plate 82 may be provided with a through hole, and the left and right ends of the lower horizontal shaft may be fixed to the through hole by the hanging arms 85. The structure of the hanging arm 85 can enhance the stability of the connector 8 so that the lower horizontal shaft can be better fixed on it. Surely, the lower transverse shaft can also be fixed on the splint 82 in other ways, for example, by means of threaded holes.

It should be noted that the coupling of the connector 8 and the track can also be realized by a sliding track and a sliding block. A sliding block may be added to the bottom of the front moving assembly 1 and the rear moving assembly 2 and sliding on the sliding track during use. The structure is simple and effective. Of course, the structure of the track 4 is not limited to the above solutions.

As a preferred solution, the track may include a front track and a rear track fixedly connected together by detachable screws. When the equipment needs to be moved, the track can be split into a front track and a rear track for easy transporting.

On the basis of this embodiment, referring to FIG. 4, in order to avoid excessively large moving distances of the two moving assemblies and to better simulate the rowing scene, a limit plug 41 may be provided on the track, and the limit plug 41 may be configured as a limit for the sliding position of the front moving assembly 1 and the rear moving assembly 2. At the same time, the restriction of the limit plug 41 can also avoid the user's muscle strain caused by excessive movement.

Among them, referring to FIG. 5, in order to facilitate the user to exert force and simulate the actions of pedaling and hand paddling in the process of rowing, the front moving assembly 1 may be provided with a pedal 11, a handle 12, and a damper. The damper can enhance the resistance during the movement process, to achieve a better exercise effect. The front moving assembly 1 may be provided with a damping assembly. A seat cushion 21 may be fixed on the rear moving assembly 2, and the user sits on the seat cushion 21 to exercise, it may be more comfortable.

It is understandable that video, and music play modules, as well as exercise time calculation module, exercise volume calculation module and other modules can also be added to the front moving assembly 1 according to requirements to increase the fun of exercise.

In another embodiment of the present disclosure, in order to make the equipment run smoothly and reduce noise, the linkage 3 can also be a belt, the transmission wheel 9 may be realized by a pulley, and the front moving assembly 1 and the rear moving assembly 2 may be respectively fixed on the belt. The fixed positions of the front moving assembly 1 and the rear moving assembly 2 may be different half sections of the closed loop. One of the two moving assemblies may be fixed to the upper half of the belt, and the other may be fixed to the lower half of the belt, realizing the function of linking of the two moving assemblies in opposite directions.

In addition, the linkage 3 can also be other long strips that can be used for traction, such as steel ropes, etc., but it is ensured that the linkage 3 has sufficient strength to prevent the linkage 3 from being torn off. Of course, the linkage 3 is not limited to the structure mentioned in this specific embodiment.

The technical solution of the present disclosure uses a linkage 3 configured to movably connect the front moving assembly 1 and the rear moving assembly 2 to the track 4. The linkage 3 may be a closed loop whose ends may be tensioned into two linear moving paths through transmission wheels. The closed loop may be roughly parallel to the track, and include a first moving path and a second moving path, respectively. The front moving assembly 1 and the rear moving assembly 2 may be fixedly connected to the first moving path and the second moving path, respectively, and driven in opposite directions when the linkage periodically rotates. This kind of simulated rowing machine uses linkages to move the front moving assembly 1 and the rear moving assembly 2 of the rowing machine in opposite directions. It can simulate the rowing movement well and exercise the muscles of the user's legs, waist, upper limbs, chest, and back, as well as the coordination of the body, with a simple and effective structure.

The technical features of the above embodiments can be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as no contradiction in the combination of these technical features is present, all should be considered to fall within the scope described in this specification.

The above examples only express a few implementation modes of the present disclosure, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present disclosure. It should be pointed out that for those of ordinary skill in the art, without departing from the concept of the present disclosure, several modifications, substitutions and improvements can be made, and these should be covered by the protection scope of the present disclosure.
